The State Ai r Resources Board (ARB) is studying the emission performance of different classes of consumer-owned
vehicles. We have contracted with Clean Ai r Vehicle Technology Center, Inc. (CAVTC) to perform this testing for
us. This letter is to confirm their legitimacy as a state contractor for this project. Your vehicle was randomly
selected and I encourage you to cooperate as fully as possible with our contractor.

The limited testing will take place at the CAVTC facilities in Hayward, California. This testing will in no
way invalidate your vehicle's emissions warranty that is required by law. All testing will be under the professional
guidance of ARB's engineering personnel and representatives of the manufacturer of your particular vehicle.

All of us in California will benefit from the results of these tests by reducing air pollution and improving
the performance and durability of vehicles sold in California. You may be assured that the ARB is only interested
in testing your vehicle. No enforcement action will be taken against you for any tempering or modification of the
emission control system or engine.

If you have any questions, you may call the ARB's In-Use Compliance Section at (818) 575-6725 or the Program
Assistance Office, toll free, at 1-800-242-4450.

Thank you for your consideration in participating in this vital program.
